I was playing a game in high resolution on my macbook retina 13, mid 2014(2.8 Core i5 (I5-4308U), i can see on temp gauge that my cpu went to 100 degree celsius(212 degree fahrenheit), and also my PECI GPU went to 100 degree celsius. 1. is this normal? 2. if I continue to play that games on my mac, will I damage my mac? I understand that on intel website, tj junction of intel Core i5 (I5-4308U) is 100 degree celsius, so 3. What tj junction means? 4. Does tj junction also apply on GPU? attached the maximum temperature recorded on my temp gauge. please share your thought.
